and we are looking at mogilefs. Mogilefs uses mysql to track file locations, and automatically replicates the number of copies required. So you can say I want at all times there to be 2 copies of this data and three copies of this other data. And when you lose a server, it detects a copy is inaccessible and starts replicating a new copy. It does the transfers over http or nfs. Because we have written the front end, we don't need a posix compliant file system, we can use the client libraries. Something to consider for people implementing large systems, and a way to avoid RAID (it's raid-ish over the network really).
